Here are some typos and mistakes I’ve found in various textbooks that don’t currently have an errata page elsewhere on the web. If you have something to add, feel free to send me a note.

- Maxwell Rosenlicht, “Introduction to Analysis”: the decimal representation on the bottom of page 26 is incorrect for a_0 a negative integer. For example, -5.12 is usually understood as being – 5 – 1/10 – 2/10^2 and not – 5 + 1/10 + 2/10^2.

- Peter Schumer, “Introduction to Number Theory”.
- page 152, problem 1(b): replace 1/(n+1)2 with 1/(n+1)^2 in the formula.
- bottom of page 128: replace 355/133 with 355/113.
